idea for floor press?

im runnint into a bit of a problem, my gym has no power rack, and no outstanding things to unrack a floor press from. i like using it in my program, and it helps my strength alot so id like to think of a better way to do it than what im doing (having a spotter help me unrack it from a bench while i lay on the floor (very inconvenient)), so any ideas of any kind are appreciated! thanks!

got 315 for an easy 2 on it today, i'm still getting used to the way to do it (doing more of a west side program now as opposed to my previous), got a 325 for a single aswell, still working on it though

dude trust me. I'm the king of scapula (ie the biggest proponent of squeezing your traps / scap together during pressing)
but i probably should work on that second part, ie bringing the bar lower.. but im usually bringing it about to the lower part of my chest.. i think it is just how i am shaped, not sure why but barbell bench (especially flat) does not agree with me and my shoulders ALWAYS do more work than my chest.. I tend to keep my elbows tucked in due to the fact that if i flare them out, i have even greater shoulder strain (except this feels more like joint strain than muscle strain)
